The package provides additional features for the LaTeX description environment, including adjustable left margin. The package also allows the user to break a list (for example, to interpose a comment) without affecting the structure of the list (this works for itemize and eumerate lists and numbered lists remain in sequence).

This packages provides a collection of programming tools for Beamer. Currently, it provides the control sequence \redefbeamertemplate for redefining a predefined Beamer template.

This package provides a BibLaTeX style, based on the Turabian Manual (a version of Chicago).

This package offers a few alternative ways for declaring and marking coordinates and drawing a line with jumps over an already existent path, which is quite a common issue when drawing, for instance, electronic circuits (like with CircuiTikZ).

This package is an extension to pgfplots. It extends the \addplot macro by a facility which allows modification of data files while they are read. With luaaddplot it is no longer necessary to pre-process data files generated by measuring devices with external scripts.

The standard letter class letter has a label feature. You can activate it using \makelabels. While in Germany window envelopes are common, printing labels is not common, and scrlttr2 has never supported label printing. Using makelabels.lco does implement a \makelabels feature similar to the standard letter classes. Currently there are (almost) no configuration features for makelabels.lco. But you may use the envlab package after loading makelabels.lco to get various configuration features.

This is the principal package in the AMS-LaTeX distribution. It adapts for use in LaTeX most of the mathematical features found in AMS-TeX; it is highly recommended as an adjunct to serious mathematical typesetting in LaTeX. When amsmath is loaded, AMS-LaTeX packages amsbsy (for bold symbols), amsopn (for operator names) and amstext (for text embedded in mathematics) are also loaded. This package is part of the LaTeX required distribution; however, several contributed packages add still further to its appeal; examples are empheq, which provides functions for decorating and highlighting mathematics, and ntheorem, for specifying theorem (and similar) definitions.

This package is an engine for calculating numerical expressions containing fractions. The numerical value of the expression is calculated with a non-expandable method and displayed in the form of an irreducible fraction or, where appropriate, an integer. This package is intended for educational purposes.

The package redefines the commands \emph and \textit so that parentheses and square brackets are typeset in an upright font in their arguments.

The package permits the user to specify easily, with the aid of self defined key-words, letters (with a logo and private) and headings. The heading may include a footer and the letter provides commands to include a scanned signature and two signees.

The package extracts information in .bib files, makes it available in the current document, and sorts lists of entries according to that information and the user's specifications. Citation and bibliography styles can then be written directly in TeX, without any use of BibTeX. The package works with all formats that use plain TeX's basic syntactic sugar; the distribution includes a third-party file for ConTeXt and a style file for LaTeX.

This package provides a useful macro to manage widow lines.

With this package you can insert vectorial coins and banknotes in euro, with stacking option. Three designs are available: full color, simple color, and simple black and white.

This dvidvi converts one DVI file into another. The output DVI file's contents are specified by page selection commands; series of pages and page number ranges may be specified, as well as inclusions and exclusions.

MathsPIC (Perl) is a development of the earlier MathsPIC (DOS) program, now implemented as a Perl script, being much more portable than the earlier program. MathsPIC parses a plain text input file and generates a plain text output-file containing commands for drawing a diagram. It produces output containing PiCTeX and (La)TeX commands, which may then be processed by plain TeX or LaTeX in the usual way. MathsPIC also outputs a comprehensive log file. MathsPIC facilitates creating figures using PiCTeX by providing an environment for manipulating named points and also allows the use of variables and maths (advance, multiply, and divide)---in short---it takes the pain out of PiCTeX.

The package provides a collection of tools, which are helpful for the creation of a LaTeX template if conditional paths for code execution are required. All the commands work both in the preamble and in the document.

pbox defines a \pbox command which adjusts the box width to that of the enclosed text, up to the maximum width given. The package also defines some associated length commands.

This package allows access to the various parameter values in TeX (catcode values), e-TeX (group, if and node types, and interaction mode), and LuaTeX (pdfliteral mode) by a hierarchical name system.

The l3sys-query script provides a method for TeX runs to obtain system information via shell escape to Lua. The facilities are more limited than the similar Java script texosquery, but since it uses Lua, l3sys-query can be used out of the box. It is suitable for use with restricted shell escape, the standard setting when installing a TeX system.

This package provides a LaTeX package which provides macros for the graphical representation of the keys on a computer keyboard.

The namespc package adds rudimentary C++-like namespace functionality to LaTeX. It may be used to declare local LaTeX commands, which can be made accessible in a later contexts without defining them globally.

VPE is a system to make the equivalent of source special marks in a PDF file. Clicking on a mark will activate an editor, pointing at the source line that produced the text that was marked. The system comprises a Perl file (vpe.pl) and a LaTeX package (vpe.sty).

This package provides the Verona theme for the beamer class.

This PSTricks package provides a really rather simple command \PstLens that will draw a lens. Command parameters provide a remarkable range of effects.
